SinC=9/41
cosC=40/41
tanC=41/9
Use ratios to solve
15 m/8 km = x m/50 km Cross multiply
15(50) = 8x
750 = 8x divide by 8 on both sides
93.75 = x
93.75 miles = 50km
Answer:
20
Step-by-step explanation:
If the three numbers are x, x+1, and x+2, then:
x (x+1) (x+2) = 990
x (x² + 3x + 2) = 990
x³ + 3x² + 2x - 990 = 0
(x - 9) (x² + 12x + 110) = 0
Since x must be a whole number, x = 9. You can also use simple trial and error to find that the three numbers are 9, 10, 11.
The sum is:
9 + 10 + 11 = 20
Answer:
25 - 3x^5
Step-by-step explanation:
-2x^4+16+2x^4+9-3x^5
Combine like terms
-2x^4+2x^4+9+16-3x^5
0 + 25 -3x^5
Answer:
B ) The slope of the triangle P and Q is equal to 2
Step-by-step explanation:
slope of a line, in this case is hypotenuse, is given by rise by run.
For triangle P
Here rise is 6 units and run is 3 units
slope= rise/run = 6/3 = 2
Also for triangle Q
rise is 3 and run is 1.5
hence slope= 3/1.5=2
hence 2 is the answer
